• Prevents chip packing and the high helix angle provides positive shearing action and rapid chip evacuation.
• Designed to machine soft materials such as aluminum, magnesium and zinc alloys. Used for slot and pocket milling, as well as plunge cutting.
• Produces a rough finish which usually requires a finishing pass with a conventional tool.
• Manufactured from M42 cobalt steel.
